Fastlane,
Logic the word comes from LOGOS sometimes translated word (meaning a proposition). In the bible (KJV) you will need to look up wisdom and understanding. Also the word "therefore" is a good word to search. You can also look up reason and contradiction etc.
If I understand your question "is the definition of logic I use the same as the one you are using when you say "source of logic- Jesus Christ."?" I would say yes. The logic we both use finds it's source in Jesus Christ (Col.2:3).
